Chemical composition and insecticidal activity of edible garland ( Chrysanthemum coronarium L.) essential oil against the granary pest Sitophilus granarius L. (Coleoptera).

The essential oil composition and biological activities ofChrysanthemum coronariumL. from three locations in Cyprus were investigated. A total of 35 components were identified in the oils representing 86.2 ± 0.7%–93.8 ± 0.0% (n = 3) of the oils. Camphor 25.2 ± 0.1%–9.1 ± 0.3%, santolinatriene 21.7 ± 0.1%–3.6 ± 0.1%, yomogi alcohol 12.6 ± 0.1%–3.6 ± 0.1%,cis-chrysanthenyl acetate 10.7 ± 0.1%–6.8 ± 0.1% and bornyl acetate 11.0 ± 0.5%–5.7 ± 0.0% were identified as the main components. Highest DPPH scavenging and PRAP activity was observed for the Lefkoşe sample (49.59 ± 0.19% (n = 5) and 812.77 ± 4.34 AU (n = 5)). Highest phytotoxic activity againstLemna minorL. was observed for the Salamis sample (100.0%). Lefkoşe sample showed the highest insecticidal activity (97.82 ± 1.79% mortality,S. granarius). Bornyl acetate/cis-chrysanthenyl acetate/hexadecanoic acid and camphor/santolinatriene/ yomogi alcohol chemotypes ofC. coronariumare proposed from Cyprus samples according to cluster analysis of the oils together with the literature data.
